Namespace: Microsoft.Data.Caching

    nd As DataCacheNotificationDescriptor _
)
'Usage
Dim instance As DataCache
Dim nd As DataCacheNotificationDescriptor

)

public:
virtual void RemoveCallback (
    DataCacheNotificationDescriptor^ nd
)

public void RemoveCallback (
    DataCacheNotificationDescriptor nd
)

public function RemoveCallback (
    nd : DataCacheNotificationDescriptor
)

Parameters

• nd
  The DataCacheNotificationDescriptor object that identifies the callback that should be removed.

Remarks

Once added, your application will continue to receive cache notifications until it removes the callback. To identify a notification, this method requires the corresponding DataCacheNotificationDescriptor object that was returned when you added the callback. To facilitate this requirement, declare your DataCacheNotificationDescriptor object at a scope that is accessible to the code in your application that adds the callback and the code in your application that removes the callback. For more information, see How to: Remove a Cache Notification Callback (Velocity).

Note

In order for your application to use notifications, you need to enable them on a named cache. Use the notificationsEnabled parameter with the New-Cache or Set-CacheConfig commands. For more information, see Cache Administration with PowerShell (Velocity).
